This project is a base station for LoRa-based satellite sensor devices such as Garden133. It includes KiCAD board design and C++ firmware. LoRa133 allows satellite sensor units to communicate using LoRa radio modules and automatically integrate with Home Assistant. I build the firmware using the Platformio build system.
This is a picture of the base station in its project box in OpenSCAD/Lora133/.
This is the PCBA documented in KiCAD/LoRa133/.
Here is what the web interface (written in Svelte) looks like:
Please see the Introducing Garden133 blog post for more information.
This device uses these libraries:
- og3. A basic C++ library for esp development in the Arduino environment.
- og3x-lora. LoRa module support for the og3 library.
- og3x-satellite. A library that helps build a satellite architecture of a base station and satellite sensors.
- Satellite Device Memory: The bridge now persists its satellite network knowledge across reboots. Restarts no longer result in a blank device list.
- Enhanced Visibility: Real-time RSSI, packet counts, and human-readable "Last Seen" timers added to the web dashboard.
- Mobile Optimized: Fully responsive web interface that fits perfectly on smartphone screens.
- og3 v0.6.1 Core: Modernized backend leveraging the latest declarative dependency and file storage improvements.
